This is the first dictionary to identify, chart, and explain in context the many proper names and place names that so famously enrich the poetry of William Butler Yeats and, just as famously, anchor that poetry to Ireland. In compiling this work, Lester I. Conner has relied upon Yeats's own prose, the principal Yeats criticism, and the writings of Yeats's friends and critics. The result is a work that warmly ushers us into the poems, where we find we are not strangers after all.
